2 Claims. or. -49

This invention relatesto the art of-window sash construction and inparticular has reference to improvements in'the art of pivoted-hingewindows.

In the art of window'sashes, it has long been known that a'double hungtype of window can be provided wherein the nrdividual sash componentsare capable of being raised and lowered vertically and are furthercapable of being hinged along one edge so as to be capable of swinginginwardly into the room for the purpose of facilitating cleaning thereof.In the past this-type of window, conveni'ently referred to hereinafteras a pivoted hingewindow, has been made with a solid frame, with' apivotal connection'being between this solid frame and'the surroundingguide track in variousways;

There has been recently introduced a new'and improved type ofwindow'sash unit that features-the use of a hollow frame member that ispreferably'a plastic extrusion that is joined together at its-cornerportions in the manner set forth in the United States Letters Patent2,742,690, issued to Aloysius T; Kunkelon April 24, 1956.

In the past it has been impossible to utilize-hollow frame windows intheart of pivoted-hinge windows due to the fact that the thin'wallsections thereof were not capable of withstanding repetitive usage.Additionally, this thin wall section-precluded the useof conventionallocking means that prevented the window from "inadvertently swinginginwardly during-the normal period of usage.

It has been discoveredthat if the pivoting and locking mechanismsrequired in such "windows are "positionediu association with-thecorner-reinforcements of "the type set forth in the above referred-toKunkel Patent"2,742,- 690, that sufficient rigidity will be providedto'facilitate' repetitive swinging and locking of-the hollowframe unit.It has further been found that if a window'of this type is operativelyassociated with 'a guide channel of similar material, improved resultscan be obtained with respect to the housing of the'customary balancingapparatus employed to stabilize the position of the window units duringuse.

It accordingly become'sthe principal object of this invention to providean improved type of vertically slidable and horizontally swingable typeofpivotedhinge sash unit having hollow frame members. i

It is a still further object 'of this inventionto provide an improvedtype of vertically slidable, horizontally swing.

able window unit having an improved type of balance incorporated thereinand further characterized bythe'provision of an improved type ofremovable stop' member;'

These and otherobjects of the invention Willbe'conie more apparent uponareading'of the following brief specification considered'and interpretedin thelight of the accompanying drawings.

Of the drawings:

Figure 1 is an elevational view of the-improved Window with thecomponent parts in closed position.

..Figure Qisasectiontaken on the lines 2-2 of Figure' 1:

Figure 3 is a sectional view taken on-thelines 3--3 of Figure 2, partsbeing broken away.

Figures 4 and 5 are perspective views ofthe reinforcing inserts utilizedinternally of the corner regions of the window.

Referring now to the drawings,- and in particular to Figure 1 thereof, awindow frame 10 is shown having an upper sash frame 12 and a lower sashframe 11, the arrangement being such that the sash frame members 11 and12 are both slidable vertically of the frame 10 and are further capableof being pivoted horizontally of the frame it upon op'erationof keymembers 13, 13.

Because'the sash members 11 and 12 are substantially identicalinconstruction, the description of one sashmember ll will be set forthas typical, with it being understood that unless otherwise mentioned,the remaining sash is of corresponding construction.

Considering first the detailed structure of sash frame elements, thesame are shown as being of the type set forth in co-pending applicationSerial No. 579,971, filed April 23, 1956, by Aloysius T. Kunkel.Accordingly, a representative frame member is shown in Figure 2 of thedrawing as being hollow in cross-sectional configuration so as toinclude a base wall 20, that is defined at its opposed edges by sidewall sections 21 and 22 respectively, with the internal surfaces of thereinforcing corner inserts being intended to contact the Wall sections20, mend-22.; p 7 V The fourth, or" remaining'side of the reinforcingcorner insert is shownhaving the" opposed edge surfaces thereofcontacting'transverse walls 23 and 24 that ex tendinwardlytoward eachother from the side walls 21 2111622, respectively. Theinboa rd edges ofthe transverse wall sections 23' and 24 co-act with a central hollow rib25 of inverted U-shaped configuration to sealand snpport' the edge ofthe pane'members -14 and 16 respectively. To this endjthe wall section23'is shown merging with an inclined wall section'26' that extendsobliquely to connect with a transverse section-27 that in turninterconnects with upright wall 25 of rib 25. In like manner, theremaining transverse wall 24, as well as upright wall 25 of rib 25, areshown interconnected with an angularly disposed wall-section'28. For thepurpose of preventing shifting "ofthe panes 14 and 16 when the same areseated, the wall sections 21 and 22 are shown as having projecting ribs31 and32 respectively that 'may terminate in bulbous tip portions, ifdesired.

The actual retention of the panes 14 and 16 with respect 'to the hollowframe members isefiectuated by the use *of resilient glazing strips 35and 36 that are respectively applied against the sash members 14 and 16to seat the same with respect to the frame member, as shown in thedrawings. In addition to the aforementioned component parts, the basesection 20 may also include a lip 41 as well as a longitudinallyextending protuberance 42; with these members 41 and 42 being designedfor co -action with the guide channel 60, as will presently bedescribed.

Considering next the structure of the upper insert designated 45 andshown best in Figure 4 of the drawings, it will be seen that the same isof right angle configuration and is provided on face 46, with a throughslot 47, within which may be received a strike plate 48, theafrangementbeing such that the strike plate 48 is doubled upon itself into U-shapedconfiguration so as to be receivable about 'the shaft 49of key 13.Additionally, the strike plate 48 may havea notch 50 provided thereonfor en gagemerit with theguide channel 60, it being understood that theent'ire strike plate 48 will be rotated and recessed within the slot 47upon turning of the key 13.

' of generally U-shaped cross-sectional configuration and includesa'bas'e portion 61 and opposed leg portions 62 and 63, with the verticalheight of this unit corresponding'substantially to the height of thewindow section associated therewith, as shown in Figure 2 of thedrawings.

For the purpose of co-acting with certain component parts of theassembled sash unit 11, the guide channel 60 further includes alongitudinally extending groove 64 as well as a slot 65 that is providedin base section 61 adjacent the uppermost end thereof, as best shown inFigures 2 and 3 of the drawing, with this slot 65 being intended forengagement by notch 50 of the strike plate 48, as best shown in Figure 3of the drawing.

Adjacent the lowermost or opposed end of the guide channel 60, there isprovided an aperture 66 through which the stud 53 may be received so asto permit attachment thereon of the flange 67, with the flange 67serving to anchor one end of the spring balance 68. The spring balance68 that is illustrated herein has its uppermost end 69 apertured so asto receive a bolt 70 that is passed therethrough for engagement with thesurrounding frame F, and in this manner the spring balance 68 isanchored at its opposed ends between the flange 67 and the bolt 70, withthe former (flange 67) being attached to the lowermost edge-of thesliding unit 11 through stud 53, while .the latter (bolt 70) is attachedto the frame F. In this manner the unit 11 may be positioned at anydesired vertical height within the frame opening and also the balance,as a result of attachment to bolt 70, does not interfere with swingingfeature of the window.

While the frame F may be of any standard type, the preferred embodimentof the invention disclosed herein contemplates the use of an improvedtype of combination stop and trim member that is generally designated bythe numeral 80 in Figure 2 of the drawings. This member 80 includes abase section 81 defined at its opposed edges by leg sections 82 and 83,the arrangement being such that the leg section 82 abuts against theplaster surface P, while the leg 83 has a return flange 84 that is bentinwardly so as to abut against the frame F and the guide channel 66, asbest shown in Figure 2 of the drawings. A groove '85 is preferablyprovided in frame F for reception of the end of flange 84.

The construction of the second window unit 12 has been previouslyindicated as being substantially identical to that of the just describedunit 11. It is to be noted, however, that in the preferred embodimentshown, the legportions 62 and 63 thereof are slightly longer than thoseprovided in the guide channel 60 that is associated with the window unit11. It accordingly follows that the over-all width of the window 12would be somewhat less so that the projecting ends of the flange 41thereof will clear the guide channel 60 that is associated with thewindow unit 11. It is believed apparent, however, that the .windowscould be made of identical size by eliminating the lip 41 and replacingthe same with a second bead and groove arrangement in this regionbetween the wall sec- .tions and 61.

In use or operation of the improved window unit, it will first beassumed that the component parts have been assembled as shown in thedrawings, and further that the spring balance 68 has been installed asshown in Figure 2 .of the drawings. It will also be assumed that acondition of normal usage is intended, and accordingly, the strike plate48 will be in the horizontal position of Figures 2,

i- 3 and 4 so as to lock the sash '11 against horizontal swingingmovement with respect to the guide channel 60. At this time the windowmay be operated in normal fashion, and may be manually lifted and closedas desired.

When it is desired to swing the window horizontally for cleaning orother purposes, it is merely necessary that the key 13 be turned degreescounterclockwise of Figures 2 and 4, at which time the notch 56 will bereleased from its engagement about the wall portion 61, with the resultthat the entire strike will rotate counterclockwise and will becomerecessed within the slot 47. At this time the window may be freelypivoted about stud 53.

When the window has been cleaned and it is desired to restore the sameto a condition of normal usage, it is merely necessary that the same behorizontally swung so that the protuberance 42 engages within thelongitudinal groove 64, and at this time the key 13 may be turnedclockwise 90 degrees so as to move within the slot 65, whereupon thenotch 50 will grip the lower edge portion of the wall section defined bythe slot 65. Upon continned rotational movement, the wall sections 20and 61 will be drawn closer together as a result of the inclineddirection of the notch 50, and when full rotational movement has beencompleted, the component parts will be in the tightly abutted and sealedcondition of Figure 2.

At this time normal operation of the window unit may be resumed.

It will be seen from the foregoing that there has been provided a newand novel type of vertically slidable, horizontally swingable windowunit of double-hung construction that features the use of sash membershaving hollow frame members reinforced at their corners. It has. beenshown how the reinforcing inserts, in addition to providing rigidity tothe sash units, also serve as a point of mounting for the variouscomponents that interconnect the'sash member and the sliding channelassociated therewith.

It has also been shown how there has been provided a new and novel typeof combination trim and stop unit that is easily positionable so as toinsure that the window unit may be accurately raised and lowered.

While a detailed description of the invention has been set forth inaccordance with the dictates of the Patent Statutes, it is to beunderstood that the invention is not intended to be so limited.Accordingly, where detailed recitations of size, composition orconfiguration have been recited, it is to be understood that the sameare intended to'have a full range of equivalence, and in this regardtheuse of hollow frames of configurations other than those set forth hereinis contemplated.

. Accordingly, other modifications of the invention may be resorted towithout departing from the spirit hereof or the scope of the appendedclaims.
